3 Description

The LMR16030 is a 60-V, 3-A SIMPLE SWITCHER®

step-down regulator with an integrated high-side

MOSFET. With a wide input range from 4.3 V

to 60 V, it is suitable for various applications

from industrial to automotive for power conditioning

from unregulated sources. The quiescent current of

the regulator is 40 μA in sleep mode, which is

suitable for battery-powered systems. An ultra-low

1-μA current in shutdown mode can further prolong

battery life. A wide adjustable switching frequency

range allows either efficiency or external component

size to be optimized. Internal loop compensation

means that the user is free from the tedious task of

loop compensation design. This also minimizes the

external components of the device. A precision enable

input allows simplification of regulator control and

system power sequencing. The device also has builtin

protection features such as cycle-by-cycle current

limit, thermal sensing and shutdown due to excessive

power dissipation, and output overvoltage protection.

The LMR16030 is available in an 8-pin HSOIC

package with exposed pad for low thermal resistance.

The new product, LM76003, requires very few

external components and has a pinout designed for

simple, optimum PCB layout for EMI and thermal

performance. See the device comparison table to
